How do we know that it is not the same bale of prayer requests on every episode of Success 'n Life?

Caught by the government for thrashing prayer requests and going right for the checks in the envelopes the Success 'n Life Ministries took to putting a bale of prayer requests on the stage in the studio. I think Trinity Broadcast Network does the same thing. I never saw anyone change out a bale or saw a date-stamp or anything. So how do we know they aren't the same bale?
